Smartphone videos could replace the doctor's joint exam for arthritis?
NCT ID NCT07740200
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This study tests whether a smartphone-based digital assessment can measure rheumatoid arthritis activity as well as a standard doctor-performed exam. Adults with rheumatoid arthritis will complete a digital questionnaire, record guided videos of their joint movements, and then have a clinician assess their disease activity using the standard DAS28 score. The researchers will compare the two scores to see how closely they agree and whether the digital tool can detect changes over time. If successful, this could lead to more convenient remote monitoring for people with rheumatoid arthritis.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Digital Disease Activity Assessment (DDAS) – a smartphone-based questionnaire and guided video recording of joint movements
- What this could lead to
- If the digital assessment matches the doctor's exam, it could offer a convenient way to monitor rheumatoid arthritis from home, reducing clinic visits.
- What could go wrong
- This is a small observational study, so the digital tool may not prove accurate enough for widespread use. It also depends on patients having a compatible smartphone and internet access.
